Julianne Hough Bikes; Diego Boneta Benches on the Beach

Diego Boneta works up a sweat as he gets in more training on the beach in Miami on Friday morning (May 20).

While the 20-year-old actor was working out with his personal trainer, Rock of Ages costar Julianne Hough was spending much needed quality time with her sister.

Julianne, big sis Sharee and her new nephew Quaid, were spotted on a bike ride around South Beach before spending some time around a pool area before heading to the actual beach for some rays.

Diego is also pictured grabbing an iced beverage and a banana from a local Starbucks after his workout.
